The brackets also comprise attachstop. -ing portions 18 and 24respectively, through Figure '2 is ase'dtion taken on a plane, inwhichrivets '17 and-25 areadapted to extend dicated by line2 2 of.Figur-e=1.in order to secure said brackets to the car Figure '3 is a section takenon a plane, side. As shown,-the brackets are preferably,

indicated by line 3- 301 Figure 1. although [not necessarily, secured tothe side Figure 4 illustrates, in elevation, a modiplate and side sillof the 'car. In order to fied stop construction. reinforce andstrengthen the brackets, ribs Figures 5 and 6 show, respectively, sec-21 and -27 connecting the body portions and tional viewstakensubstantiallyon theplanes attaching portions thereof, are employed.

The body portions of said brackets are provided with recesses and 28which are substantially T-shaped in section in order to conform to thesection of the elongated member 15. Extending across the lower bracketmember is a wall 30, provided with an opening 29. The purpose of thisopening is to permit proper disposal of any foreign matter which mayfind its way into the socket portion formed by the recess and the wallmember. It is to be noted that, with the exception of said wall member,the two bracket members are substantially identical in construction.

The member 15, in its operative position, is adapted to have one'ofitsends seated within th socket portion of the bottom bracketand supportedtherein. The upper end of said bar is adapted to extend into andslightly beyond the recessed portion of the upper bracket member, asclearly shown in Figure 1 of the drawing. The purpose'of thisconstruction is to permit ready removal of said member 15 for repairsthereon or for replacement thereof. The member 15 is. shown as bowed orarena-ted at 32 for a portion of its length intermediate the brackets.The extent of this bowed or arcuated portion is merely a matter ofchoice, depending on proper functioning of the'member; Ad-

jacent the upper edge of the member 15 is a bolt 33, extending throughone of the flanges thereof. This bolt is shown as disposed a substantialdistance below the lower edge'of the upper bracket, this distance beingsomewhat smaller than the length of'the member 15 disposedwithin thesocket portion of the lower bracket member. The purpose of this bolt isto prevent accidental vertical displacement of the member 15 to such anextent that the lower'end thereof would be removed entirely from thesocket portion of the lower bracket member. 7

It is apparent from Figure 1 that the bowed portion 32 of the member 15is presented toward'the door in the direction of the opening movementthereof. It is apparent, therefore, that as the door reaches the openposi tion it will contact with said bowed portion which, because of theflexibility thereof, will provide a cushioning effect for the door andat the same time be effective to stop the opening movement thereof. Inthis way the danthe 1 brackets may be secured at any desired spacedpoints on the car side. As shown in Figures 5 and 6, however, thesebrackets are secured,

preferably, to the side plate and side sill of the car. The lowerbracket 52 is formed with a body portion 53 and with a flange 56 throughwhich rivets 59 are adapted to extend to attach said bracket to the sidesill 58. A bottom wall 5% is shown which, in connection with the bodyportion 53 of the lower bracket, provides a socket adapted to receiveand support the lower end of the member 50.

In order to support the upper end of said member a bracket 60 isprovided. This bracket comprises a body portion 61, a wall portion 62and attaching portion 63, all of Y which are substantially similar tothe corresponding portions of the lower bracket member heretoforedescribed. The body portion, together with the wall portion 62,constitute a socket or recess portion into which the upper end of themember 50 is extended. The bracket is shown as secured to the dependingflan e of the side plate 68 by means of shouldered rivets 69. Theserivets extend through elongated slots 64: formed in the attaching flange63. The slots have positioned in them the shoulders of the rivets 69,for a purpose hereinafter referred to. The upper part of the attachingflange 63 has, extending horizontally therefrom, and preferably integraltherewith, a flange 66 which is adapted to overlie and be supported uponthe horizontal web 67 of the side plate. Projecting from the upperbracket is an extension which, together with a portion of said brack--et,'forms an angular recess. Seated in this recess is a locking memberwhich, in the present form, is disclosed as a bolt 7 0 having a nut 71thereon. It will be noted that the nut 71 is adapted to be positioned inthe angular recessed portion of the bracket so that unauthorized removalof said nut, when the bracket is properly positioned, is prevented. Thepurpose of the bolt and nut structure above referred to is to preventaccidental vertical movement of the upper bracket with a consequentrelease of the upper end of the member 50 from the socket portion ofsaid bracket. 6

As heretofore noted, the connection of the upper bracket to the side ofthe car is made by means of rivets extending through elongated slots inthe attaching portion of said bracket. The purpose of such connection isto permit, when desired, vertical movement of the bracket for removaland replacement of the member 50. By using a shouldered rivet,attachment of the bracket is effected and at the same time binding ofthe attaching portion is avoided. It is noted that, with the exceptionof the drainage opening 55 provided in the wall 54' of the lowerbracket, the upper and lower brackets are of substantially similarconstruction.

It is believed, in view of the foregoing, that the operation of the doorstop shown in Figures l, 5 and 6 will be apparent.

In order to remove and replace the member 15 shown in Figure 1 of thedrawing, it is only necessary to remove the bolt 33 and to draw saidmember vertically upward out of the lower bracket member and through theslot provided in the upper bracket member. It is to be understood thatsufiicient clearance between the member 15 and the recess in the upperbracketmemberis provided so that said member 15 may readily bewithdrawn. It is also to be understood that, in the constructions shownin Figures 1 and 4 of the drawing, the bowing or arcuating of themembers 15 and 50, respectively, are shown exaggerated for the sake ofclarity.

In order to remove and replace the member 50 shown in Figure 4 of thedrawing, the bolt may be rotated from the inside of the car so that thenut 71 will ride off said bolt. When this has been done the bracket 60may be raised vertically on rivets 69 and the member 50 may readily beremoved. After replacement of a new member the upper bracket may againbe lowered so as to receive the upper end of said member within thesocket portion of said bracket and the bolt and nut 70 and 71 may. againbe properly positioned.

It is apparent that numerous changes may be made in constructionsillustrating the preferred embodiments of the invention withoutdeparting from the spirit thereof. It is to be understood that all suchchanges are contemplated in this invention, the scope of which islimited only by the claims appended hereto.
